12,011,205 p DOMESTIC-WATER, BOILER 1 Ivan Turner, Richmond, EnglandApplication September '1, 1934, SerialNo'. 743,142 V t In Great BritainMarch 15, 1934 8 Claims. (o1.12 s '132) This invention relates todomestic water boilers for houses or apartments with self-contained (hotwater supply, and more particularly to cokejfired or like boilers whichare employed for supplying hot water' 'for baths, radiators and otherdomestic purposes, independently-cf cooking stoves; theseindependentboilers, as commonly fitted in kitchens or living rooms, are*open to the objection that they do not provide the comfort of openfires, but on the other hand they may render the rooms unnecessarilywarm when.

used tosupply-hotwater during the summer months.

The main object of the present invention isto provide for the supply] ofhot water from the independent 1 boiler, without inevitably heating thekitchen or other' room in which the boiler is fitted, and for theseparate or controlled-heating of theroom, without requiring a secondfireplace recess and flues, the apparatus employed being adapted to takethe place of the ordinary independent boiler; 7

According to this invention, I provide a hot water boiler of theindependent type, that is in dependent of a. cooking stove, with whichboiler I combine an open fireplace having its framework combined withthat of theboiler. In the back of the open fire place, whichconveniently forms part of the boiler front and may slope forward fromabove the level o'fnthe burning fuel towards the top front of theboiler, I provide a hinged or detachable door or doors, giving access tothe front bars of the boiler fire, so that these bars can be removed'forcleaning or laying the boiler fire; normally the door or doors willbe kept closed, so as to retain the. heat, but they may be left openwhen the boiler fire is burning, if it be desired to warm the room whenthe open fireplace is not in use; The boiler. firebox is .fittedwithaloose grid or bottom bars, which i may be of the rocking 'oroscillatingqtype for front of the open fireplace. t The invention ishereafter described with refriddling the fire, with. control means atthe jerence to. the accompanying drawings, in

Fig. 1 is an elevation showing the open fireplace as seen from thefront, parts being broken Fig. 2 is a plan of the boiler, showing the'flues 1 in section.

is arranged behind the open fireplace b, as clear- '10 ly seen in Fig.3. The sloping back of the open fireplace is arranged to form part ofthe boiler frontc, which extends across the full width of the boilerandmay support the back fire-brick b of the open fireplace the sloping partbulg- 5 'ing forward above the level of this fire-brick and extendingtowards the top plate (1 of the boiler which overhangs the openfireplace. The side frames e (see Fig. 4), which support the firebrickcheeks b of the open fireplace, are'tied together by a flanged plate 2secured by setscrews c these side frames e are arranged flush with thesides of the boiler" so as to form extensions of thecorrespondingfboiler walls, and their rear edges areshaped to fitagainst the sidesof the boiler front c. Ifhe front frame ,1

of the open fireplace extends up as far as the top plate (1 of theboiler, its transomf supporting a hood or canopy 9 above the openfireplace. 'The frame members e f and the boiler "front 0 are securedtothe boiler by means of long horizontal studs h screwed into the boilerwalls at the upper iand'lower frontcorners of the water spaces, withnuts h fitted to the ends of v these studs projecting through the'framef; the

fianged'plate e is also secured to the boiler "front c by bolts 6? atthe back of the open fireplace.

In the sloping portion 0 of the boiler front,

there'is provided a, rectangular opening 0 into which thefront bars 2'of the boiler fire are'fitted;

' these bars serve to retain the fuel heaped up on the boiler fire, itbeing customary to stoke boil- "ers of this kind at long intervals, sayevery'twelve hours. The bars iwhich may be separate or cast together,are accommodated inside the bulge in which the opening c -is formed andare held in place by notches c at the upper and'lower ends of theopening, the bars being removablethrough "theopening'qc (after liftingthe bars clear of d the lower notches) for cleaning or laying the boilerfireL The opening c which thus gives access tothe boiler firebox, isadapted to beclosed by a jdetachabledoor or doors 7' provided with books7' at the sides, these hooks engaging over wedge-shaped lugs c on theedges of the opening; a hole or holes 7' may be provided on the front ofthe door to facilitate its removal and. replacement.

The boiler is fitted with bottom fire-bars in the form of a loose grid70 which rests upon lugs or ledges k cast on the inner walls of theboiler a (see Figs. 3 and 4); beneath this grid, there is provided atransverse shaft Z supported on two brackets l secured to the boilerfront 0, the shaft having two pairs of oppositely extending arms Zconnected by transverse bars Z lying beneath the grid is towards itsfront and rear ends. A crank arm m dependent from the middle of theshaft 1 is connected by a rod m to a knob or handle m at the front ofthe grate, so that the boiler fire can be shaken or riddled byoscillatting the shaft Z so as to rock the grid is. I a The openfireplace I) is shown as fitted wit a removable grate bottom it havingrear supports n secured upon the flanged plate e the 'front edge n ofthe grate bottom is turned up to hold the fuel in place and it issupported for example on pegs f projecting inwardly from the frame 1,the underside of the grate bottom being notched at f? to fit over thesepegs so that it cannot slip forward accidentally.

In the bottom of the frame, and extending from front to rear under bothfires, there is fitted a large ashpan o, the front 0 of which isprovided with a handle 0 and a suitable draft-regulator o forcontrolling the admission of air to the boiler fire; the front 0 mayalso be notched at 0 for the passage of the rod m which is guided atthis point by a hole or eye m is a vertical rib e below the front of theflanged plate e Above this ashpan and underneath the open fireplace, Iprovide a second ashpan p carried on the flanged plate 6 which is ofopen hexagonal shape, as seen in Fig. 5, the pan p normally coveringthis opening, so as to exclude all draft from above this pan into theboiler fire, and also from below this pan tothe open fire, and the airfor the latter being admitted through a regulating shutter p inthe frontp of this second ashpan, which is fitted with a handle p The ashescollecting in the second pan p can be tipped into the large bottomashpan o by sliding the former outwards, as indicated in Fig. 4, andtilting it up, a scraper bar p? hinged at n beneath the grate bottom itserving to clear the pan as itis drawn out, and the ashes then fallingthrough the open center of the plate e into the bottom ashpan o.

The water spaces at the vertical sides a of the boiler increase in widthfrom the line where the sloping portion 0 of the boiler front begins tobulge forward over the open fireplace b; thus there is a relativelysmall firebox at the bottom of the boiler, but from a few inches abovethe bottom bars 70 the combustion space widens out towards the front, ascan be seen in Fig. 3, so that ample heating surface and fuel capacityare provided. An opening :1 in the fiat top plate at of the boilerallows fuel to be added after removal of the lid d the smoke outlet qbeing located directly behind'the firing'hole 11 Suitable tappings r r1' for the flow, return and drain-off water pipes are provided,togetherwith one or more manholes r if desired.

- The combustion gases from the open fire place 1), which forms thefront of the combined apparatus, escape from the top of the slopingbackc and beneath the boiler top plate (2, which extends over the openfireplace, into horizontal fiues s at the two sides of theboiler andthence ordinary open fireplace, as seen in Fig. 1., and at the same timeto retain the heat radiated from the exterior of the boiler a; the spaceabove the boiler top plate d may then be closed in by extending thefront frame 1 upwards above the canopy g and providing a hinged door m,which when opened (as shown in dotted lines in Fig. 3) allows the fuelto be fed to the boiler; a handle 10 with a suitable catch enables thedoor to be opened and closed, hinged door stays 10 being provided ifdesired. If preferred, however, I may dispense with the door 10, andleave the space above the boiler open as illustrated in Fig. 6, the topplate d of the boiler being in that case formed with a suitable beadingd or the like. A guard fence may be placed round the sides and back ofthe firing hole 01 or this fence may be arranged at the edge of the topplated, as indicated at a: in Fig. 3.

The boiler a and front frame i may rest upon a base 1 at the front ofwhich there is arranged a loose tray 2 to catch any cinders falling fromthe ashpans or from theopen fireplace.

'By this combination of an open fire place b with the hot water boilera, I provide a highly adaptable boiler, which can be employed not onlyindependently of the cooking stove, but either alone, with or withoutheating of the room by opening or closing the door 7' above the openfire place, or in conjunction with the open fire when the room requiresheating, or can be put out of operation, the heating of the room beingthen provided, if required by a fire in the open fire place I) alone.Under normal conditions, the boiler will be maintained in operation forsupplying hot water for domestic purposes; the heating of the room willthen be provided by the opening 0 part of the heat from. the boilercombustion space being transmitted into the room. When heat from theboiler combustion space is not needed to heat the room, the door 7' willbe closed; similarly the door 7' will be closed whenall of such heat isrequired to heat the water in the boiler, but in this case a separatefire can also be provided in the open fire-place, if heating of the roomis desired. Lastly if the boiler is out of operation, and it is requiredto warm the room without delay or for a short period, a fire can belighted in the open fire place alone. Both fires are preferably arrangedto burn the same fuel, e. g. coke, anoz either or both may be providedwith gas ignition means, as indicated at b in Fig. 3, but it will beunderstood that either the boiler or the open fire place, or both, maybe gas-fired, suitable supply pipes and burners being provided as wellknown in the art.
